I THINK I did these right! seemed too easy so I feel like I messed up somewhere.
and table with margins for 2nd section
A. Consider a population consisting of the following values, which represents the number of ice cream purchases during the academic year for each of the five housemates. 8, 14, 16, 10, 11 a. Compute the mean of this population. 11.8 b. Select a random sample of size 2 out of the five members. 8 and 14 c. Compute the mean and standard deviation of your sample. 11 d. Compare the Mean and Standard deviation of your sample to the entire population of this set (8,14, 16, 10, 11). Mean of sample is less then mean of population. standard deviation is smaller as well. Suppose that the sample size n = 100 and the population proportion p = 0.95. Does the sample proportion p have approximately a normal distribution? yes Since p = .95, q = .05. p * n = .95 * 100 = 95 q * n = .05 * 100 = 5 What is the smallest value of n for which the sampling distribution of p is approximately normal? 6 beca...
